Circuits

As resistors are added in series to a circuit, the total resistance will...

• decrease

• remain the same

• increase

• fluctuate

What is a Parallel circuit?

• Has more than one path

• Has only one path

• Is a type of series circuit

• Is used in all electrical devices

The picture shows an electrical circuit. This circuit is a series circuit because:

• The same current flows through all three light bulbs.

• The voltage is divided among the light bulbs.

• Each light bulb can be turned on or off independently.

• The light bulbs are connected in parallel.

An incomplete circuit is shown.
To complete the circuit, a wire should be placed from —

• Point A to Point B

• Point A to Point C

• Point A to Point D

• Point B to Point D

This circuit has more than one loop. When one light goes out, the others stay on.

• series circuit

• parallel circuit

• open circuit

• closed circuit

What is a circuit that only has ONE path for electricity to flow?

• parallel circuit

• series circuit

• open circuit

• closed circuit

In a parallel circuit if one of the light bulbs burns out the rest _________.

• can still light up

• will all go out

• will flicker briefly

• will dim significantly

Which best describes a simple series circuit?

• Electricity flows along one pathway.

• Electricity flows in multiple pathways.

• Electricity is stored in a battery.

• Electricity is generated by a solar panel.

As the resistance of a circuit increases, the current will...

• increase

• stay the same

• decrease

• fluctuate

Which uses more energy? Series, Parallel
